该段代码展示了如何使用反射操作Android系统的SmsManager类，实现双卡手机中选择特定卡（GMS或CDMA）发送短信的功能。通过检查getSimStateGemini方法是否存在来判断设备是否为双卡，并根据SIM卡状态保存可用卡信息。

try {

      Class<?> smsManagerClass = null;
         Class[] divideMessagePamas = { String.class };
         Class[] sendMultipartTextMessagePamas = { String.class,String.class, ArrayList.class, ArrayList.class,ArrayList.class, int.class };
         Method divideMessage = null;
         Method sendMultipartTextMessage = null;
         smsManagerClass = Class.forName("android.telephony.SmsManager");
         Method method = smsManagerClass.getMethod("getDefault", new Class[]{});
         Object smsManager = method.invoke(smsManagerClass, new Object[]{});
         divideMessage = smsManagerClass.getMethod("divideMessage",divideMessagePamas);
         sendMultipartTextMessage = smsManagerClass.getMethod("sendMultipartTextMessage", sendMultipartTextMessagePamas);
         ArrayList<String> magArray = (ArrayList<String>) divideMessage.invoke(smsManager, content);

sendMultipartTextMessage.invoke(smsManager,phone, "", magArray, null, null,phoneType);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

通过反射发现sendMultipartTextMessage多了一个phoneType的参数，这个参数就是这只用GMS还是CDMA卡发送的。phoneType获取方法，iTelephony.getActivePhoneType();//1=GSM,2=CDMA

public static void initIsDoubleTelephone(Context context){
boolean isDouble = true;
Method method = null;
Object result_0 = null;
Object result_1 = null;
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
try {
//只要在反射getSimStateGemini 这个函数时报了错就是单卡手机（这是我自己的经验，不一定全正确）
method = TelephonyManager.class.getMethod("getSimStateGemini",new Class[] { int.class });
//获取SIM卡1
result_0 = method.invoke(tm, new Object[] { new Integer(0) });
//获取SIM卡1
result_1 = method.invoke(tm, new Object[] { new Integer(1) });
} catch (SecurityException e) {
isDouble = false;
e.printStackTrace();
//System.out.println("1_ISSINGLETELEPHONE:"+e.toString());
} catch (NoSuchMethodException e) {
isDouble = false;
e.printStackTrace();
//System.out.println("2_ISSINGLETELEPHONE:"+e.toString());
} catch (IllegalArgumentException e) {
isDouble = false;
e.printStackTrace();
} catch (IllegalAccessException e) {
isDouble = false;
e.printStackTrace();
} catch (InvocationTargetException e) {
isDouble = false;
e.printStackTrace();
} catch (Exception e){
isDouble = false;
e.printStackTrace();
//System.out.println("3_ISSINGLETELEPHONE:"+e.toString());
}
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(context);
Editor editor = sp.edit();
if(isDouble){
//保存为双卡手机
editor.putBoolean(ISDOUBLE, true);
//保存双卡是否可用
//如下判断哪个卡可用.双卡都可以用
if(result_0.toString().equals("5") && result_1.toString().equals("5")){
if(!sp.getString(SIMCARD, "2").equals("0") && !sp.getString(SIMCARD, "2").equals("1")){
editor.putString(SIMCARD, "0");
}
editor.putBoolean(SIMCARD_1, true);
editor.putBoolean(SIMCARD_2, true);
} else if(!result_0.toString().equals("5") && result_1.toString().equals("5")){//卡二可用
if(!sp.getString(SIMCARD, "2").equals("0") && !sp.getString(SIMCARD, "2").equals("1")){
editor.putString(SIMCARD, "1");
}
editor.putBoolean(SIMCARD_1, false);
editor.putBoolean(SIMCARD_2, true);
} else if(result_0.toString().equals("5") && !result_1.toString().equals("5")){//卡一可用
if(!sp.getString(SIMCARD, "2").equals("0") && !sp.getString(SIMCARD, "2").equals("1")){
editor.putString(SIMCARD, "0");
}
editor.putBoolean(SIMCARD_1, true);
editor.putBoolean(SIMCARD_2, false);
} else {//两个卡都不可用(飞行模式会出现这种种情况)
editor.putBoolean(SIMCARD_1, false);
editor.putBoolean(SIMCARD_2, false);
}
}else{
//保存为单卡手机
editor.putString(SIMCARD, "0");
editor.putBoolean(ISDOUBLE, false);
}
editor.commit();
}
